摘要
采用连续衬拉复合工艺线路对铜铝双金属管成形规律进行研究 ,全面探讨了变形量和后序的热处理工艺对界面强度的影响 ,以及在成形过程中组元金属的变形规律。界面强度受变形量及热处理工艺影响较大 ,且组元金属存在不均匀变形规律 ,这为合理制订铜铝双金属管拉伸复合工艺提供了依据。
The forming regulation of Cu/Al bimetal tube was studied by many passes plug drawing. The influence on the interface bonding strength affected by the total reduction in cross sectional area and heat treatment after drawing and the rule of deformation during the drawing process were investigated. The experimental results prove that interface bonding strength is mainly influenced by the total reduction in cross sectional area and heat treatment, and heterogeneous deformation exists in producing bimetal tubes, which will provide key data for drawing Cu/Al bimetal tube.
